function xout=crp2(varargin)
%CRP2 Creates a cross recurrence plot/ recurrence plot and the LOS.
% CRP2(X [,Y [,param1,param2,...]) creates a cross recurrence
% plot/ recurrence plot from the embedding vectors X and Y.
% Results can be stored into the workspace. Further it
% is possible to estimate the line of synchronization (LOS)
% in order to get the nonparametric time-relationship between
% the two considered systems.
%
% R=CRP2(X,M2,T,E) uses the additionally dimension M2, delay T
% and the size of neighbourhood E and creates a recurrence
% plot of X.
%
% R=CRP2(X,Y,'distance','nonormalize') creates a
% distance coded matrix plot without normalization
% of the data.
%
% Allows to change the parameters interactively by
% using a GUI.
%
% The embedding dimension M is given by the size of the
% N x M matrix X and Y; if the matrix Y is not specified,
% a simple recurrence plot is created.
%
% Parameters: additionally dimension M2, delay T and the
% size of neighbourhood E are the first three numbers
% after the data series; further parameters can be used
% to switch between various methods of finding the
% neighbours of the phasespace trajectory, to suppress
% the normalization of the data and to suppress the
% GUI (useful in order to use this programme by other
% programmes).
%
% Methods of finding the neighbours.
% maxnorm - Maximum norm.
% euclidean - Euclidean norm.
% minnorm - Minimum norm.
% nrmnorm - Euclidean norm between normalized vectors
% (all vectors have the length one).
% fan - Fixed amount of nearest neighbours.
% omatrix - Order matrix (disabled).
% opattern - Order patterns recurrence plot.
% distance - Distance coded matrix (global CRP, Euclidean norm).
%
% Normalization of the data series.
% normalize - Normalization of the data.
% nonormalize - No normalization of the data.
%
% Suppressing the GUI.
% gui - Creates the GUI and the output plot.
% nogui - Suppresses the GUI and the output plot.
% silent - Suppresses all output.
%
% Parameters not needed to be specified.
%
% Current limitation: for higher speed in
% output the whole matrix of the recurrence
% plot is in the work space - this limits
% the application of long data series.
%
% Examples: a = sin((1:1000) * 2 * pi/200); % pendulum's location vector
% b = cos((1:1000) * 2 * pi/200); % pendulum's velocity vector
% plot(a,b,'.')
% crp2(a(1:500),b(1:500),'nonorm','euclidean')
%
% b = sin(.01 * ([1:1000] * 2 * pi/67) .^2);
